Decrease of the responsiveness of beta-2 adrenoceptors of diabetic rat knee joint blood vessels in acute inflammation
Beta-2 adrenoceptors in blood vessels are one of the active factors that play a role in regulation of tissue blood flow. in diabetic angiopathy, responsiveness of these receptors is decreased, while that is increased in inflammation. According to these opposite effects, the aim of this study was to investigate the vasodilatory response of knee joint blood vessels to salbutamol (Beta-2 adreno...

متن کاملPRE- AND POSTJUNCTIONAL α-ADRENOCEPTORS IN RABBIT ARTICULAR BLOOD VESSELS
Previous in vitro work on rabbit knee joint vessels showed that vasoconstrictor effects of nerve stimulation and administration of α-adrenoceptor agonists were mediated predominantly by α1-adrenoceptors5,9 The present experiments were performed to assess the nature of α-adrenoceptor subtypes within these blood vessels in vivo. Dose/response relationships for adrenaline and noradrenaline pr...
متن کاملEvidence for lack of innervation of beta-2 adrenoceptors in the blood vessels of the gracilis muscle of the dog.
Cardiac /S-l adrenoceptors respond to sympathetic nerve stimulation (SNS), but it is not clear that SNS evokes fi-2 adrenoceptor-mediated vasodilation. Sensitivity of B adrenoceptors to catecholamines and to SNS was evaluated in dogs. Norepinephrine (NE) and epinephrine (E) were equipotent vasoconstrictors (femoral artery blood flow or gracilis autoperfusion pressure) before aadrenoceptor block...
متن کاملPharmacological characterization and anatomical localization of prejunctional beta-adrenoceptors in the rat kidney.
1. The subtype and anatomical localization of beta-adrenoceptors mediating facilitation of stimulus-induced overflow of noradrenaline ('prejunctional beta-adrenoceptors') are not conclusively known to date. The present study was undertaken to characterize these receptors by use of pharmacological methods as well as to define their localization (prejunctional or postjunctional) with radio-ligand...
